As a northern Ontario boy, half the people the people i knew had sauna’s. Growing up it was normal to sauna with the adults and they would often have beer, outside the sauna but in between jumping in the lake and such. Beer and sauna went hand in hand. It is funny how completely crazy that sounds to me now as a health conscious adult. Lol. I did actually have some non-alcoholic beer with the sauna this past summer which was pretty nice!
The fact that the cardiovascular benefits of sauna are dose-dependent, according to the KIHD study, makes the case in favor of sauna even more compelling. Great video!
I always thought it was a way of looking at bodies with fewer clothes, in a country where the weather is not usually conducive to that. Other countries use beaches for that. 😅
Since the UK smoking ban I had been wondering what to do instead of going to the pub. After all I don't drink anyway. Sauna is brilliant. Maybe we can turn some of the Pubs that are going out of business into Sauna and red-light therapy !
My wife and I, age 51 and 49, sauna at least once per week. Always on Friday, always with 2 or 3 beers per session. There was a large influx of Finnish immigrants to our area in the 70's and 80's, and that is part of the sauna culture.
I notice Nic said to avoid alcohol but when you are on vacation , you might drink a lot and there are saunas in the hotels. That is how you end up drunk in a sauna.

I’ve been doing sauna for over 2 decades but more regularly since after the COVID lockdowns and I have never felt better, in terms of my health and how it improves my immune system. I’ve been spending in the sauna (80-90C) for a minimum of 1/2 hour in the summer and near an hour in the winter with cold showers in between (somehow the colder the shower, the longer I can stay in the sauna afterwards. Apart from all the benefits mentioned in this video, I’ve read about how sweating can help to detox the body and enhance autophagy. Not to mention how the infrared from sauna can activate the production of melatonin by our mitochondria. Not to mention how sweating unblocks the pores and improves complexion. However, one still needs to be aware of the potential harms that sauna can cause. Last year, I saw a man who collapsed after spending about an hour in the sauna, he had been in and out, doing around 10-15 mins inside max, always sitting at the lower level. According to the staffs there who was taking care of him, his BP was down to 40 systolic. I spoke to him the next day, he told me he used to have high blood pressure but have been on BP lowering meds for over a decade. From what I can deduced, he was probably completely dehydrated which lowered his BP and caused him to faint. For people who have medical issues, especially low blood pressure, they need to make sure to be well hydrated and not stay in there for too long. Stay healthy! 😘

Sauna usage in Europe is a relaxing and sometimes social activity. No one brings their cellphones or headphones into the sauna. From my observation in the states people take their electronic devices into the sauna. Maybe there is a benefit to the social or disconnection component that would not be observed in the U.S.

It's good to put in controls like blood pressure, but you have to consider, what if the sauna decreased blood pressure. Then, controlling for it obscures one of the benefits. Of course, with an RCT you can actually measure if blood pressure drops in the sauna group more than in the placebo group.

I understand this is a study/discussion on the health benefits of sauna. However, I feel that the whole discussion is somehow sidetracked in a bad way. There is a quite different whole sauna culture here in Finland, that most groups of foreign people including health enthusiasts don't seem quite to understand, or even totally misunderstand. It is true that quite a few people even drink heavily connected to a visit to sauna, which is never good as such alone. If one drinks tradiotionally a beer or two afterwards, it should be okay. Almost everybody has access to one or several saunas here. The tradirional (and the best) way to enjoy, is to visit a sauna a couple of times after a week of work at a lakeside (absolutely no hurry) and then have a swim in a lake, and then sit at the lakeside during a long summer evening peacefully to cool off with friends, and maybe have a beer. Repeated if one feels like it.
Interestingly in this graph 9:00, the HSP concentration before the 10th sauna is higher than before the 1st sauna, so there may be a chronic increase. Though the difference is small compared to the variation, so I don't know if it's statistically significant.
Hey Dr. Nick! I’ve noticed that countries that traditionally Sauna, lack Sunshine and that the reported benefits of each overlap. Is there any evidence that Sauna benefits people in sunny climates?
I reckon a sauna in a cold country or in winter has more benefits than a hot one or in summer. Also if the main or real benefit of a sauna is raised nitric oxide then you can get that by humming, which works out a lot cheaper. Humming can increase nasal NO levels 15- to 20-fold compared to quiet exhalation
By far the most available “sauna” for the most people in the US is a sauna blanket, but then there are warnings about electromagnetics (I’m no expert!) so, are sauna blankets ok, or not? Are there studies?
Regarding alcohol consumption in the sauna: in Russia it's kind of a cultural phenomenon to mix the two. People would go to a sauna complex featuring the sauna room, a cold water pool and a table filled with alcoholic drinks and snacks, and then alternate between them for a couple of hours.
If you fallow sauna strickly you know that the best way to do it is after spending 10 to 15 minutes in sauna you are supposed to jump in cold water so what it does to your veins is hot relaxes the veins cold contracts the veins so if you do this regularly your veins stay flexible which will prevent hart diseases related to vains which get hard and cause high blood pressure and so forth..falow the ice man wim Hoff? talsk about this..
In Northern Ontario, Canada, the First Nations people (Cree and Ojibway) became very close and sympatico with immigrants from Finland --- and this led to a lot of intermarriage --- because the Finns used the sauna, which is identical to the First Nations "sweat hut." In both cultures, the sweat treatment is seen as a cultural marker and a spiritual practice. The custom is common to aboriginal peoples across the subarctic Taiga regions of boreal forest from Fennoscandia across Siberia and into Alaska and throughout Canada.
Does hot bath in bath buckets with water up to neck level give same effect? Water can heat your body up in lower water temperature than air in saunas, so I imagine that you cauäb get sanäne effects that way. Or do you need to heat up the head and breathe hot air to?
Would love to see a comparison of effects between Japanese-style baths and sauna. A Japanese bath fits into most people’s homes (even apartments) better than a sauna.
@@broccool2300Japanese homes all have bath tubs, even most of the smallest apartments. Japanese regularly take hot baths every evening before bed. No onsen but the OP’s point stands
@@ryanvacation7319 Those are way more expensive and at no shortage of used space. You can convert a shower space into a sauna just as you could use the same space to put in a bathtub. I have a portable infrared sauna that I put in my home gym and it only cost me $200.
I wonder if there is any contribution from near infrared and it's effects on cell signalling? Like Interaction with Cytochrome c Oxidase (CCO) in Mitochondria, Reactive Oxygen Species (ROS) and Redox Signaling, Calcium Ion (Ca²⁺) Signaling... etc.... As in, i wonder if the near infrared contribution has been teased out from the more abundant mid and far infrared typical of most saunas...
I suspect it has, just by the nature of the heating method of most saunas. I guess you could bring an IR meter in to one and check. It would likely be low. IR or RL therapy needs to be much closer to the skin than the typical sauna heating element is.
@@geoff_onYT I know only 1 Finnish person who does not go to sauna on regular basis. In Finland its really hard to find non users... 5.5 million population with 3 million saunas. The only "hopelessly confounded" factor is nationality. Now I think I go to warm up my sauna for its much healthier activity than arguing in RUclips ^^
My problem with sauna is that it wipes me out for the rest of the day.....at least if i do the twenty minutes like they recommend. Electrolytes help but there's not getting much done after. All I want to do is sleep it off. Great before bed I suppose but that doesn't fit my schedule. Really good for the skin though. I noticed that dry, flakey skin around my nose and forehead vanished after doing sauna for a while. I can do 10 or maybe 15 but I have to bounce once I start feeling my heart start pounding hard. Maybe if you're a runner with a super-cardio system you wouldn't have this problem and 20 minutes would be a breeze. Just like weight lifting though and the soreness that follows I can tell good things are going on physically.
Saunas speed up the dehydration rate in your body. That’s what’s causing your “pounding heart” while in the sauna. I feel terrible (tired/lifeless) also after being under excessive heat. I’d rather remain at slightly elevated room temperature (75-85) to feel my best.
In addition to electrolyte water, you probably need to take binders when you sauna. I used to feel like you when I was super mold toxic but now that I've been doing it a long time I feel great afterward.
I drink about 12-16 ounces of heated water with salt added immediately prior to entering the sauna. This helps your body deal with the rapid dehydration and salt loss through sweating, but heating the beverage doesn't counteract the sauna's heat effects. Basically, it's about as warm as you can make it while still being able to drink it straight down without needing to sip due to heat.
@@Physionic Low LDL is causing Alzheimer's, Parkinson's and ADHD and of course anxiety. I changed my mind about that, so please, someone make video if possible.
With population of 5.5million people Finland has over 2 million saunas, so with any measure sauna is absolutely not limited to your economical status. Everyone in Finland has some access to sauna. Home, Apartment, shared Sauna in apartment buildings, or swim halls or pubic saunas, hotel, Gym or second on in cottage by the lake.... Paper mill workers can have sauna after their work shift if they wish, same with Police and firemen, Ice Breakers and Ships... Finland is known for its work life balance, so every walks of life has chance to relax after hard work day or -week.
In Sweden we usually do sauna after training, if we do it socially, for example if we go with some friends on the weekend, do sauna and ica bath, it's almost exclusively in combination with beer. And we don't do this for health reasons of course.
Physionics Insiders: I've watched a few of your videos recently (great content) and am interested. Before signing-up it would be great if you expounded (perhaps in a video?) on what you typically explore in-depth there. For instance, in this video, you mention more info about the best sauna protocols. Do you, for instance, share thoughts/data on infrared (IR) vs traditional sauna therein?
Everyone pretty much have sauna in Finland so it has nothing to do with money. Finnish people do it because its f cold. Walking is still prob first better to do if you think how you spend your time.
i never have, but a few beers in the sauna sounds like a great time, at least before learning about the sudden cardiac death aspect. But it wouldn't surprise me to learn if some Canadians, Eastern Europeans, or Russians, etc., throughout history, weren't strange to drinking alcohol in the sauna
Other studies showing in sauna have the sweating so water loss and then body working to increase blood volume so with this more epo which in turn is big benefit for endurance athletes- please can comment on this from all your reviews?
All very interesting, thank you. However, what about the benchmarks for and definition of SAUNA? For example, how long is a "sauna bath" and at which temperature is the sauna area? Also, does it include the water-on-the embers ritual. These are all components and correlations that should be mentioned in the analysis. Or, not?
I think that a hot bath allows a break for the mitochondria (less energy needs to be produced and other metabolic functions can be focused on) you may quote me on that
My mother in law have been told by her doctor to never go to saunas as she's had blood clots before and is now on blood thinners permanently. I find that contra indicating.
Think of it like this. If you're allergic to vegetables then don't eat vegetables. Doesn't make vegetables are good for most people but not for this person untrue. Sauna increases heart rate and drops blood pressure if you've got heart disease this could theoretically kill you therefore drs may tell patients aka unwell people not to sauna but this doesn't make it untrue that saunas are good for well people. Also I'm a Dr and a physiologist in intensive care. Hope that helps
@MegaPoliyo yes saunas increase heart rate, but so does exercise. Heart diseased patients are not adviced against exercise, quite the contrary. Again, from all the health benefits that increases longevity, I'd find it a bad idea for such a patient to completely avoid saunas. I'd just urge the person to be careful and exit the sauna if she feels bad. Same with infrared light use.
Unfortunately, Attia has a long history of promoting beliefs that are refuted by the scientific evidence. It has made him wealthy though.

Dr. Rhonda Patrick was the original researcher who spoke out about all those benefits of saunas and more. She presented this many years ago. Hats off to Rhonda.
Sauna and then jump into a hole chopped out of the ice in the lake. I read that you blood pressure will spike and heart rate jump. I wonder if that is safe? I know at our family cottage at the lake in Manitoba the neighbors had a sauna right beside the lake and would chop a big square hole in the ice and do this. Get steaming hot and run out fast and jump in the drink (lake).
It's pretty common in Russia to drink vodka in Saunas. Not sure how this tradition formed, bout thousands of people do that regularly, people who can are often overweight, drinkers and smokers, all in one. And yes, there is nothing good in that combination, yet people keep doing it.
I'd love to see some objective data on the benefits of hot exercise, both with and without infrared lights. I use a Hotworx studio, where I do interval training @130 F two to three times weekly. The traditional saunas in my city are more like AIDS-sharing spaces than what the Fins had in mind.
The adjusted model does not accout for the fact that the people who have the time to go to sauna all the time do this while still doing all the other things the reference group. In other words, they can accomplish more in a time unit. Maybe this is due to the sauna goers having a higher IQ and/or other similar factors that are not adjusted for.
Pretty sure hot rocks or flame or whatever ”produces” infrared light. But certain wavelengths can have certain effects. So not the same but similiar. Normal sauna can be like small workout, infrared sauna more like recovery.
Or steam shower. I can only stand a max of 10 minutes at 110 degrees F with near 100% humidity. But I'm motivated to do it every night because it helps me sleep much better. But with dry saunas, people spend ~30 minutes in there at 180 degrees F. Infrared are apparently slightly lower temperatures. Very different experience, either way.
Do you think a hot shower can do the same thing? I know personally I’ve raised my heart rate significantly in a hot shower, and lowered my blood pressure immediately afterwards.
These studies were randomizing into different groups and not giving the non-sauna group a placebo? Why? You could give them a sugar pill so they think they are getting a treatment and will get the positive psychological effects, even if it's quite unlike a sauna regimen.
That tends to be my thought process, too, Richard. Maybe there's literature indicating it's not effective, because it's too different? Always been baffling to me.
Eh... Bastu (Sauna) is NEVER done without beer - everyone knows that. And they are accessible to anyone (albeit not at home for most city dwellers) no matter income. /Greetings from Sweden
Finns don't do sauna for the health benefits, it just happens to be part of the culture. Most people do sauna just for fun and drink beer in there, and they have a lot of other unhealthy habits. Coming from a finn, saying that people who already are interested in health are more likely to do sauna is simply not true. Most low income houses, especially rural ones still have a sauna. Also many low income people go to public saunas.
I detest heat. I am wiped out and feel awful be it humid or dry heat. Dry is better, but I feel as though I am drowning in a wet sauna. I cant breathe.

Also if the main or real benefit of a sauna is raised nitric oxide then you can get that by humming, which works out a lot cheaper. Humming can increase nasal NO levels 15- to 20-fold compared to quiet exhalation
By far the most available “sauna” for the most people in the US is a sauna blanket, but then there are warnings about electromagnetics (I’m no expert!) so, are sauna blankets ok, or not? Are there studies?
Amazing and easy to understand thank you
Regarding alcohol consumption in the sauna: in Russia it's kind of a cultural phenomenon to mix the two. People would go to a sauna complex featuring the sauna room, a cold water pool and a table filled with alcoholic drinks and snacks, and then alternate between them for a couple of hours.
If you fallow sauna strickly you know that the best way to do it is after spending 10 to 15 minutes in sauna you are supposed to jump in cold water so what it does to your veins is hot relaxes the veins cold contracts the veins so if you do this regularly your veins stay flexible which will prevent hart diseases related to vains which get hard and cause high blood pressure and so forth..falow the ice man wim Hoff? talsk about this..
you sure that doesn't damage the veins?
Great, thank you 👍
In Northern Ontario, Canada, the First Nations people (Cree and Ojibway) became very close and sympatico with immigrants from Finland --- and this led to a lot of intermarriage --- because the Finns used the sauna, which is identical to the First Nations "sweat hut." In both cultures, the sweat treatment is seen as a cultural marker and a spiritual practice. The custom is common to aboriginal peoples across the subarctic Taiga regions of boreal forest from Fennoscandia across Siberia and into Alaska and throughout Canada.
The real OG's knew this shit with Dr. Rhonda Patrick almost a decade ago
Does hot bath in bath buckets with water up to neck level give same effect?
Water can heat your body up in lower water temperature than air in saunas, so I imagine that you cauäb get sanäne effects that way. Or do you need to heat up the head and breathe hot air to?
20 minutes of heat exposure, doesn't matter
Would love to see a comparison of effects between Japanese-style baths and sauna. A Japanese bath fits into most people’s homes (even apartments) better than a sauna.
There is no way that a Japanese style onsen is easier to have than a sauna.
@@broccool2300Japanese homes all have bath tubs, even most of the smallest apartments. Japanese regularly take hot baths every evening before bed. No onsen but the OP’s point stands
@@ryanvacation7319 Those are way more expensive and at no shortage of used space. You can convert a shower space into a sauna just as you could use the same space to put in a bathtub. I have a portable infrared sauna that I put in my home gym and it only cost me $200.
We in Uk used to have properly hot baths before we all went to showers. It was fabulous
I don’t need sauna, I have menopausal heat flashes.
Does sauna help or hinder midlife hormonal fluxuations ?
My sauna is a gift. In fact I’ll hop in now. lol. They are about $150 on Amazon too. Relatively affordable.
I wonder if there is any contribution from near infrared and it's effects on cell signalling? Like Interaction with Cytochrome c Oxidase (CCO) in Mitochondria, Reactive Oxygen Species (ROS) and Redox Signaling, Calcium Ion (Ca²⁺) Signaling... etc.... As in, i wonder if the near infrared contribution has been teased out from the more abundant mid and far infrared typical of most saunas...
I suspect it has, just by the nature of the heating method of most saunas. I guess you could bring an IR meter in to one and check. It would likely be low.
IR or RL therapy needs to be much closer to the skin than the typical sauna heating element is.
"Please be good for me, please be good for me..." 🙏
Anything on sauna causing cataracts?
Peter goes instantly offtrack: even people on welfare go to sauna here.
but that doesn't mean the data isn't hopelessly confounded. as he says, there could be 100 important reasons sauna users are different to non-users.
@@geoff_onYT I know only 1 Finnish person who does not go to sauna on regular basis. In Finland its really hard to find non users... 5.5 million population with 3 million saunas. The only "hopelessly confounded" factor is nationality. Now I think I go to warm up my sauna for its much healthier activity than arguing in RUclips ^^
My problem with sauna is that it wipes me out for the rest of the day.....at least if i do the twenty minutes like they recommend. Electrolytes help but there's not getting much done after. All I want to do is sleep it off. Great before bed I suppose but that doesn't fit my schedule.
Really good for the skin though. I noticed that dry, flakey skin around my nose and forehead vanished after doing sauna for a while. I can do 10 or maybe 15 but I have to bounce once I start feeling my heart start pounding hard. Maybe if you're a runner with a super-cardio system you wouldn't have this problem and 20 minutes would be a breeze.
Just like weight lifting though and the soreness that follows I can tell good things are going on physically.
Saunas speed up the dehydration rate in your body. That’s what’s causing your “pounding heart” while in the sauna. I feel terrible (tired/lifeless) also after being under excessive heat. I’d rather remain at slightly elevated room temperature (75-85) to feel my best.
Good personal feedback - thanks for sharing
In addition to electrolyte water, you probably need to take binders when you sauna. I used to feel like you when I was super mold toxic but now that I've been doing it a long time I feel great afterward.
@@cindianderson9443 What do you mean by "binders"?
I drink about 12-16 ounces of heated water with salt added immediately prior to entering the sauna. This helps your body deal with the rapid dehydration and salt loss through sweating, but heating the beverage doesn't counteract the sauna's heat effects. Basically, it's about as warm as you can make it while still being able to drink it straight down without needing to sip due to heat.
Not sure why I am watching. I do not live near a public sauna and can not afford one. Wish I could afford one. I love them.
Last Tuesday at 9:28am, I changed my mind on connection between LDL and mental disease. Why nobody makes a video about that? It's about time.
wat.
@@Physionic Low LDL is causing Alzheimer's, Parkinson's and ADHD and of course anxiety. I changed my mind about that, so please, someone make video if possible.
With population of 5.5million people Finland has over 2 million saunas, so with any measure sauna is absolutely not limited to your economical status. Everyone in Finland has some access to sauna. Home, Apartment, shared Sauna in apartment buildings, or swim halls or pubic saunas, hotel, Gym or second on in cottage by the lake....
Paper mill workers can have sauna after their work shift if they wish, same with Police and firemen, Ice Breakers and Ships...
Finland is known for its work life balance, so every walks of life has chance to relax after hard work day or -week.
guess i should stop drinking beer in the sauna 😅
But you have to replenish the fluids you sweat out. As long as you some cardio you should be ok. Right?
@@patcusack6252 alcohol is a known carcinogen.. and there is no safe dose like there is no safe amount of cigarettes to smoke. Drink water
In Sweden we usually do sauna after training, if we do it socially, for example if we go with some friends on the weekend, do sauna and ica bath, it's almost exclusively in combination with beer. And we don't do this for health reasons of course.
Do we need to differentiate IR vs. traditional saunas? Which kind has more health benefits?
Physionics Insiders: I've watched a few of your videos recently (great content) and am interested. Before signing-up it would be great if you expounded (perhaps in a video?) on what you typically explore in-depth there. For instance, in this video, you mention more info about the best sauna protocols. Do you, for instance, share thoughts/data on infrared (IR) vs traditional sauna therein?
Average life span in Finland is 82 years.
Little sunlight and drinking culture probably hurts them a lot.
@ we Americans have an average lifespan of 77.5 years. Looks like the sauna helps!
People probably a lot more sensible in Finland they probably don’t jump over the counter and fight the fast food worker over their nuggets
Actually it's the cold climate that helps, but sauna does take stress away.
Everyone pretty much have sauna in Finland so it has nothing to do with money. Finnish people do it because its f cold. Walking is still prob first better to do if you think how you spend your time.
What do you think about consuming spices like cloves, ginger, cinnamon and turmeric as a way to reduce mortality risk ?
For anyone who has no access to saunas, will a hot shower or hot bath yield at least part of the benefits, like the hot shock proteins for example?
Yes, most likely at least some part of it like HSP and NRF-2 activation
i never have, but a few beers in the sauna sounds like a great time, at least before learning about the sudden cardiac death aspect. But it wouldn't surprise me to learn if some Canadians, Eastern Europeans, or Russians, etc., throughout history, weren't strange to drinking alcohol in the sauna
Sitting in a sauna while listening to a video about saunas
Please can you speak on red light therapy for injury recovery, joint pain, and post-surgery
12:09 very typical in Finland to drink like a sponge when in sauna xd
Other studies showing in sauna have the sweating so water loss and then body working to increase blood volume so with this more epo which in turn is big benefit for endurance athletes- please can comment on this from all your reviews?
Drinking in the sauna is very common on Finland (I do it too sometimes). Its usually only a beer or two most of the times however😄
😱
Same in Sweden, although much less than in Finland.
Sauna, drinking, and swimming goes hand in hand.
It’s how Finns cope w depression.
i think its simple the answer that is , if one is about to die he probably cant go to sauna to begin with he is ether at home or at a hospital .
I dont have a suana. I do have access to a bath. Any evidence comparing sauna to hot baths? Thanks.
Look at Dr Rhonda Patrick if you want to know more but she says its the same...
Hi. I wonder if you've looked in to capsaisin? No effect?
All very interesting, thank you. However, what about the benchmarks for and definition of SAUNA? For example, how long is a "sauna bath" and at which temperature is the sauna area? Also, does it include the water-on-the embers ritual. These are all components and correlations that should be mentioned in the analysis. Or, not?
Is there much difference between sauna and running on a hot summer day?
Is there a distinction between traditional sauna and infrared sauna? Access to one or the other may be difficult.
I think that a hot bath allows a break for the mitochondria (less energy needs to be produced and other metabolic functions can be focused on) you may quote me on that
My mother in law have been told by her doctor to never go to saunas as she's had blood clots before and is now on blood thinners permanently. I find that contra indicating.
I wonder if there’s studies out there relating to blood clots and sauna use
Think of it like this. If you're allergic to vegetables then don't eat vegetables. Doesn't make vegetables are good for most people but not for this person untrue. Sauna increases heart rate and drops blood pressure if you've got heart disease this could theoretically kill you therefore drs may tell patients aka unwell people not to sauna but this doesn't make it untrue that saunas are good for well people. Also I'm a Dr and a physiologist in intensive care. Hope that helps
@MegaPoliyo yes saunas increase heart rate, but so does exercise. Heart diseased patients are not adviced against exercise, quite the contrary. Again, from all the health benefits that increases longevity, I'd find it a bad idea for such a patient to completely avoid saunas. I'd just urge the person to be careful and exit the sauna if she feels bad. Same with infrared light use.
Unfortunately, Attia has a long history of promoting beliefs that are refuted by the scientific evidence. It has made him wealthy though. He is telegenic and articulate which no doubt helps explain his popularity on social media and among alternative health believers and health influencers of the shock/horror persuasion.
However, it means that I automatically question anything he says.
I partly agree , however i’ve watched few
interesting and inspiring clips by him . He is too serious in his appearance , i’m concerned if that’s good for longevity ….. I think it’s too much. about health and longevity ….on utube generally … people who do not have the right knowledge get only more confused -do this do not that , eat that eat not that …. best wishes from scandinavia
@@katarina8225 Thank you and best wishes to you from Australia.
It is important to fact check everything that Attia claims since many of his claims are contrary to what the totality of the evidence shows
Dr. Rhonda Patrick was the original researcher who spoke out about all those benefits of saunas and more. She presented this many years ago. Hats off to Rhonda.
For those who really don’t have the money to do regular saunas. Would soaking in a hot bath provide any of the sauna benefits?
I sauna 3 times per week at my local gym. Is there an optimal temperature and time spent per session?
20 minutes 200degrees
What about the increase in HGF Dr. Rhonda Patrick says results from sauna ?
Very interesting. That makes sense because warmth can spike glucose.
why type of Sauna is most beneficial?
Sauna and then jump into a hole chopped out of the ice in the lake. I read that you blood pressure will spike and heart rate jump. I wonder if that is safe? I know at our family cottage at the lake in Manitoba the neighbors had a sauna right beside the lake and would chop a big square hole in the ice and do this. Get steaming hot and run out fast and jump in the drink (lake).
Has anyone studied the effects of sauna with a control group taking a hot bath and/shower,?
If I do my HIT and sauna regularly I am off blood pressure medication. I have to stop taking it I get light headed from super low BP
I wonder if you get the same effects from hot baths.
20 minutes yes
It's pretty common in Russia to drink vodka in Saunas. Not sure how this tradition formed, bout thousands of people do that regularly, people who can are often overweight, drinkers and smokers, all in one. And yes, there is nothing good in that combination, yet people keep doing it.
I'd love to see some objective data on the benefits of hot exercise, both with and without infrared lights. I use a Hotworx studio, where I do interval training @130 F two to three times weekly. The traditional saunas in my city are more like AIDS-sharing spaces than what the Fins had in mind.
Is an hour in a hot bath as healthy as an hour in a sauna?
Glad somebody finally said his name right 😂
Can you evaluate Urolithin A
Have video
Keep up your potassium and magnesium people
So who's the interviewer?
He changed his mind on sauna at sauna 😂😂
The adjusted model does not accout for the fact that the people who have the time to go to sauna all the time do this while still doing all the other things the reference group. In other words, they can accomplish more in a time unit. Maybe this is due to the sauna goers having a higher IQ and/or other similar factors that are not adjusted for.
It would be interesting to see if there is a difference in health benefits between classic sauna and infrared sauna...
Been wondering about that for a long time but can't find definitive data.
Tough one to tease out, I’d need to look further
Pretty sure hot rocks or flame or whatever ”produces” infrared light. But certain wavelengths can have certain effects. So not the same but similiar. Normal sauna can be like small workout, infrared sauna more like recovery.
Or steam shower. I can only stand a max of 10 minutes at 110 degrees F with near 100% humidity. But I'm motivated to do it every night because it helps me sleep much better. But with dry saunas, people spend ~30 minutes in there at 180 degrees F. Infrared are apparently slightly lower temperatures. Very different experience, either way.
@@Physionic Same for a hot bath. Is it just about heating up the body?
Do you think a hot shower can do the same thing? I know personally I’ve raised my heart rate significantly in a hot shower, and lowered my blood pressure immediately afterwards.
These studies were randomizing into different groups and not giving the non-sauna group a placebo? Why? You could give them a sugar pill so they think they are getting a treatment and will get the positive psychological effects, even if it's quite unlike a sauna regimen.
That tends to be my thought process, too, Richard. Maybe there's literature indicating it's not effective, because it's too different? Always been baffling to me.
New haircut is fitting. Also, is this the final title of the video?
Ha! A mistake :) thanks
Eh... Bastu (Sauna) is NEVER done without beer - everyone knows that. And they are accessible to anyone (albeit not at home for most city dwellers) no matter income. /Greetings from Sweden
Finns don't do sauna for the health benefits, it just happens to be part of the culture.
Most people do sauna just for fun and drink beer in there, and they have a lot of other unhealthy habits.
Coming from a finn, saying that people who already are interested in health are more likely to do sauna is simply not true. Most low income houses, especially rural ones still have a sauna. Also many low income people go to public saunas.
I detest heat. I am wiped out and feel awful be it humid or dry heat. Dry is better, but I feel as though I am drowning in a wet sauna. I cant breathe.

I do sauna daily, cannot afford to do that at home, but here in Finland, every swimming hall has saunas so there goes your bias towards a certain $$$ class....
